Having a repeated Acan issue...

[BBestvin]

I've been having this issue the last couple weeks within my nano reef. When blowing out the rocks or stirring up the sand, my acans have been looking angry. They've come back each time, but I'm worried they eventually won't. I should also mention my dendro also does the same thing. About two weeks ago I accidentally did a water change with too high salinty water. They all did the same thing, but have come back once I corrected the issue. During the salinty issue, I thought the dendro was done for, but thankfully it came back as well. Any thoughts on this?

Elevate them a little and moderate light and water flow
Stirring sand likely elevating phosphate and nitrate
Siphoning is best bet

Thanks for responding! It's very odd to me that this is happening a lot lately with these Acans and the Dendro. The other coral in the tank seem to stay open and happy when I'm blowing out the rocks. I should mention that I'm not really stirring the sand, but mostly just moving the topmost layer, as I have some cyanobacteria on the sandbed. Could getting the cyano into the water column cause corals to close up?

Cyano and Dino will irritate them
If you’re seeing signs of cyano, there’s a chance that your phosphate and/or nitrate is elevated and that will do it

I've been doing weekly water changes for about 6 weeks now and am still seeing cyano. I think the driving factor could be that I had a pistol shrimp die underneath one of rocks. I'm guessing it decaying could be causing these issues because I don't have the tank overstocked and I don't overfeed. Do you know how long it could take for something like that to decay? That could cause the issue I believe, correct?

Whenever I blow off rocks or water towards my scans they do the same thing. They also do that when lights are out but come out fully during lights on. I think it's normal, mine seem sensitive to any flow changes

Only thing i can do with acans is kill kill them.
